Ruptured Small Intestinal Stromal Tumor Causing Concurrent Gastrointestinaland Intra-Abdominal Hemorrhage: A Case Report

摘要

Gastrointestinal stromal tumors (GISTs) originate from mesenchymal cells throughout thegastrointestinal tract. A common symptom is gastrointestinal hemorrhage; intra-abdominalhemorrhage is relatively rare. There are few reports of GIST presenting with both types ofhemorrhage concurrently. A 77-year-old man was admitted to our hospital because of melenaand anemia (Hb: 4.7 g/dL). Computed tomography revealed a small bowel tumor andhigh-density fluid in both the small intestine and the pelvic floor. We diagnosed a smallintestinal tumor with concurrent gastrointestinal and intra-abdominal hemorrhage, andperformed emergency surgery. The tumor arose from the small intestine and was ruptured. Wefound hemorrhage in the pelvic cavity and performed partial small intestine resection.Pathological findings revealed that the tumor was positive for c-Kit protein and wasdiagnosed as GIST. The patient was discharged from the hospital on postoperative day 9 andreceived imatinib 1 month postoperatively. We experienced a very rare case of rupturedGIST originating from the small intestine associated with both gastrointestinal andintra-abdominal hemorrhage. We also reviewed the relevant literature.
